Import Tips
• Provide detailed dimensional specs and pressure ratings in commercial invoice to confirm casing classification over tubing
• Obtain pre-shipment inspection certificates for alloy content to comply with quota restrictions on certain steel imports
• Label clearly as 'drill pipe casing' to prevent reclassification as general mechanical tubing
